将域别名映射到IIS6中的虚拟文件夹

Question

我怎么能去映射域别名，如domainAlias.co.za下，以一个虚拟文件夹，例如mainDomain.co.za ，让所有请求domainAlias.co.za实际上得到的服务mainDomain.co.za/domainAlias ？

Answer 1

A URL Rewriter like IIRF lets you do this.

The rules would be:

RewriteCond %{HTTP_HOST}  ^(?!mainDomain)([^\.]+)\.co\.za$
RewriteRule ^/(.*)$       /%1/$1   [L]   

In English, this rule says: if the host is NOT maindomain.co.za, but still ends in .co.za, then rewrite the URL so that it is prepended with /domainAlias/. With this rule, you get:

input                         output
-----                         ------
http://foo.co.za/a.php        http://main.co.za/foo/a.php
http://foo.co.za/a.aspx?r=1   http://main.co.za/foo/a.aspx?r=1

You can also go one level further and make the rewrite conditional on the presence of the directory, something like this:

RewriteCond %{HTTP_HOST}   ^(?!mainDomain)([^\.]+)\.co\.za$
RewriteCond c:\wwwroot\%1  -d
RewriteRule ^/(.*)$        /%1/$1   [L]   

This says: if the host is not maindomain.co.za, AND the directory c:\\wwwroot\\domainAlias exists, then rewrite to prepend ....

But in that case you might instead want to do the converse - test for lack of existence of the directory - and redirect to a 404:

RewriteCond %{HTTP_HOST}   ^(?!mainDomain)([^\.]+)\.co\.za$
RewriteCond c:\wwwroot\%1  !-d
RewriteRule ^/(.*)$        -   [NF]   

NF = 404

you can also do [F] which is a 503 (Forbidden).

IIRF works on IIS5, IIS6, or IIS7.

您可以使用路由。

System.Web.Routing

Answer 3

I haven't used it, but IIS has a URL Rewrite Module that can import Apache mod_rewrite rules . There is also a document that compares IIS URL Rewriting and ASP.NET routing . With some research, you should be able to get that working.
